Proof that Billyburg has jumped the shark, this resto in the sleek, Miami-esque King & Grove hotel could well be in Tribeca. Indeed, Paul Liebrandt comes from expense-account buster Corton in that very same hood. Precious menu themes marked as Raw, Sea, Land and Share. Poshie priced dishes are haute, cheeky takes on foie gras, fish & chips, short ribs. Yet it stoops to happy hour frolickings, where cocktails like the Joan Rivers and the Huckleberry Mojito can be had for a sixer. Sprawling interior exhibits industrial cool not found on N. 6th St.
